\n Extrusion is used to build mesh elements of plus one
dimension than the input ones. Any line or planar element can be
extruded. Line elements will extrude into quadrilateral plane elements.
Triangular and Quadrilateral plane elements extrude into Pentahedron
and Hexahedron solids respectively.
<em>To use extrusion:</em>
<ol>
<li>From the \b Modification menu choose the \b Extrusion item or click
<em>"Extrusion"</em> button in the toolbar.

<li>specify the IDs of the elements which will be extruded by
selecting them in the 3D viewer or select the whole mesh or
submesh,</li>
<li>specify the vector along which the elements will be extruded,</li>
<li>number of steps.</li>
</ul>
<li> <b>Generate Groups</b> checkbox allows copying the groups of
